Students learn about water quality testing and basic water treatment processes and technology options. Biological, physical and chemical treatment processes are addressed, as well as physical and biological water quality testing,...

An information page on understanding drinking water safety. It covers legislation, contaminants, private wells, water testing, water filters, and boiling water.

In this experiment, students will test the quality of a water sample by observing the number of coliform bacteria. Coliform bacteria are found in human intestines and a large amount can indicate water contamination. Lesson plan gives a...

This field investigation will be in collaboration with Eagle Bluff Environmental Learning Center in Lanesboro, MN link to Eagle Bluff. It will include chemical, biological, and physical tests. The chemical tests will include kits where...

In this instructional activity, students will monitor the school's water meter to get an overview of the total water consumption and the cost of that water which will help them develop an idea of water consumption patterns and how much...

Students develop an understanding of the water cycle and water catchments. This learning module is divided into introductory, developmental, and culminating activities, and also has several assessment strategies. Resource sheets...

In this environmental science lab you will chemically test a nearby creek or pond for dissolved oxygen, pH, alkalinity, hardness and turbidity. This is a field test and will determine the water quality of standing body of water. The lab...

Provides information on what to do after a flood to protect well water from contamination, the testing of private well water, and protecting private well water.

After observing the local aquatic environment and testing the water quality, students formulate a testable hypothesis. They next choose a second location, collect samples to bring to school, and test the water quality. Data is organized...

In this unit, students will try to improve stream quality and reduce human impacts by taking action.This Advanced Water Quality unit is packaged into three smaller parts: Part 1: Stream Habitat Assessment; Part 2: Macroinvertebrate...

Use this lesson plan to introduce students to testing water sources for pathogenic microorganisms. Students will learn methods for groundwater sampling to evaluate water quality. Lesson plan includes student worksheets.

Students perform an experiment comparing the impacts of CO2 on salt water and on fresh water. In a short demonstration, students examine how distilled water and seawater are affected differently by increasing carbon dioxide in the air.

This EPA resource provides instructions for using Secchi disks and transparency tubes to measure water clarity.

This site talks about the nitrate and nitrogen forms that can be found and how to test for it. Includes illustrative diagrams and graphs.

The water quality at a local pond or stream is tested, and examined for organisms. Students record their data and observations and analyze the information. A pH chart showing what aquatic organisms can live at different pH levels is...

Choosing two different powders, students will evaluate the properties of the materials and if the materials, when mixed with 50 ml of water, make a mixture or solution. They will examine the difference between a mixture and a solution...

Read this summary of how water cleaned and tested.

In some part of the world there is not enough fresh water for every use. If things are done differently water re-use can be very effective. Learn here about ways we can change the world. Wastewater, if properly treated can be a resource...

In this science activity, students investigate the water cycle by testing the water evaporated from leaves (transpiration). They investigate concepts of evaporation and the movement of water through the different states of the water...

Through research of community water assessment and reports, students will make a video presentation of the local water resources.

This is a scientific investigation where students establish what macro-invertebrates live in a local water habitat (stream, pond, aquarium), and predict how healthy the water is. They then test the water quality, record the data, and...

After analyzing samples of water from local lakes, students will perform tests on water from two locations, compare the results, and complete a lab report. They will then examine maps to determine factors that may have had an impact on...

Provides information about water quality, contamination in private wells, well construction and pump installation for private wells, a list of laboratories certified to test for bacteria and other contaminants, recommendations for...

This two-month project requires a nearby stream or river to use for testing. Students use river monitoring equipment to conduct water tests, fish observation, insect identification and to collect data related to physical properties of...
